A whole house UV water filter for Riverhead, Orewa Or Warkworth can provide all parts of your home with clean filtered water that is suitable for drinking.

A whole house UV water filter in Riverhead, Orewa Or Warkworth, like most water filters, will have the water going through several stages of filtration. One of the stages is the use of carbon filters that remove both small and large impurities, as well as volatile organic compounds, pesticides, insecticides and industrial solvents. The filtered water will then pass through a UV chamber where it is subject to disinfection from ultraviolet rays. You can also get whole house filters that use only ultraviolet rays if you are reasonably sure of the quality of water and are sure it does not contain any solids. The ultraviolet rays are produced by a UV lamp, whose light is considered germicidal. This lamp is protected by a quartz sleeve, that permits UV rays to pass through.

As the water passes through the UV chamber all living organisms in the water get exposure to the ultraviolet light that then attacks the genetic code of the organisms and eliminates their ability to reproduce and function. The UV light is able to destroy almost all the microorganisms that may be present in water, up to 99.99 per cent, and it does not require any addition of chemicals. Ultraviolet technology has been used for decades by municipalities and by commercial water bottling plants and has now found its way into whole house filters. The UV light is produced in closed chambers and therefore is not of any harm to its users. It is a chemical-free process that creates no by-products. It is simple and safe to use.

It is important that before a UV system is installed, all the pipelines in the home are disinfected through the introduction of a chlorine solution that is allowed to stand in the pipework for some time.

A UV system works best if all particles larger than 5 microns are effectively filtered, and the best Riverhead, Orewa Or Warkworth UV whole house filters are those that have a single or two-stage filtration system using carbon and other filters, that removes all solids.

UV systems must not be installed directly on PVC pipe, as UV light rays can cause the PVC to rot as it would when exposed to sunlight. A minimum length of 12 inches after the UV filter can allow the UV light to dissipate.
